What I'm looking for

I'm looking for remote opportunities where I can build complex, high-scale React or Web3 products, own frontend delivery end to end, and contribute to architecture, quality, and product outcomes.

I've modernized Minterest's core DeFi platform, cutting bundle size by 25% and production incidents by 15%, while building a new Web3 MVP in two months with a reusable 40-component UI library.

At Hexacore, I architected and launched a React Telegram Web App for 2M+ players, supporting 100K peak concurrent users and 1K+ daily multi-chain transactions across TON, Solana, and Telegram Stars. I've also delivered healthcare platforms, enterprise SaaS, CRM systems, and greenfield products across six companies.

I build end-to-end frontend and full-stack modules with React, Next.js, TypeScript, and Node.js, with a focus on maintainable architecture, accessible interfaces, performance, and reliable delivery. I also contribute through technical interviews, code reviews, design systems, testing, and mentorship.
